minor comment tweaks so that all the source files are covered)

just the zero-length ones; this fixes multiple replaces occurring with
them in conjunction with "*"

the last of the low-level input overhaul: make the global shortcut list
use NANO_NO_KEY to represent no key value, add the NANO_HISTORY_KEY
sentinel value, add support for many more escape sequences for those
terminals that generate them, add DB's extensibility tweaks to
do_yesno(), make ASCII 128 act like Backspace when -d is used, add
various cleanups to the low-level input functions, and make the last of
the low-level input routines use the new low-level input functions

that works better and is less hackish

display_string() function, and convert some parts of nano to use it


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1552 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

static int there and free up space for one more flag; also make a few
misc. cleanups involving #ifdefs

- Move docs to doc/:
  + texi doc to doc/texinfo/
  + original manual pages to doc/man/
  + translated manual pages to doc/man/xx/

- Memory leak fixes for files.c:do_insertfile(),do_browser(), nano.c:do_spell(), and search.c:do_replace() (David Benbennick)

- Fix nano crashing when searching/replacing an invalid regex (try ^*).  Changed regexp_init() to return 1 or 0 based on regcomp()'s return value and search_init to exit with an error message (sorry Jordi)


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1406 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- Fix constant curos updates from obliterating other system messages, and fix statusbar message length. Affects files.c:load_open_file(), nano.c:main(), search.c:findnextstr(), winio.c:statusbar() and do_cursorpos() (David Benbennick)


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1403 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- search.c:do_search(), do_replace_loop() - Fix edit_update call to use CENTER instead of current_x (related to David Benbennick's fixes for spelling)


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1398 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

General - Fix subexpression replacement to work consistently.  Affects search.c:replace_regexp() and utils.c:strstrwrapper() (David Benbennick)


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1393 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- search.c:do_replace_loop() - Fix various bugs having to do with replace string length and positioning (David Benbennick)


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1392 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- Added search/replace history log.  Flag -H, --historylog. Flags HISTORY_CHANGED and HISTORYLOG, added entries in nanorc.sample, new functions log_history and save_history (Ken Tyler)

git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1365 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- search.c:do_gotoline() - Don't call blank_statusbar_refresh() so if there's an error returned in multibuffer mode, we can actually see it

- Fixed awful scrolling in do_int_speller. Problem was findnextstr() calling edit_update(), though screen updating is not its business Added checks in do_search() and do_replace_loop() to do the checks.  It really should not be done here, as some function in winio.c should handle this, but I can't seem to find a good place to put this check

git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1350 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

- search.c:do_replace_loop() - Remove check for answer being a blank string, presumed to a PICO_MODE holdover, but it stops us from doing a blank spelling replacement

More bits left over from getting rid of pico mode, no more CLEAR_BACKUPSTRING, woo!  Also reodered flags to remove gaps


git-svn-id: svn://svn.savannah.gnu.org/nano/trunk/nano@1339 35c25a1d-7b9e-4130-9fde-d3aeb78583b8

Completely removed PICO_MODE, as with the search/replace history patch we should have the extended functionality we can without being incompatible with pico
