The relative path could be . or .. or even empty, which is uninformative.

This fixes the last part of https://savannah.gnu.org/bugs/?47798.

Error messages about lock files should not get overwritten by purely
informational messages, only by alerting ones.

This fixes https://savannah.gnu.org/bugs/?47963.

Either the selected file was changed, or a file or directory was chosen
(and the Enter key virtually pressed), or a shortcut was executed.  So,
just go and read the next key.

This fixes https://savannah.gnu.org/bugs/?47944.

If during startup there are multiple error messages, currently only the
last one remains and can be read.  To improve on that, introduce a short
pause between error messages -- even if it's not enough to read them all,
at least the user will be aware that there are multiple ones.

This also causes a few error messages to beep that currently don't beep,
such as when a file is unwritable.

When doing a PageUp or PageDown in the browser, don't move the highlight
to the first line in the same column, but keep it in the same relative
position of the screen.  If we're already on the first or last page,
move the highlight to the first or last line, but keep it in the same
column.  If we're already on the first or last line, only then move it
to the first or last entry.

CONST_UPDATE is only relevant when in the main menu, not when in the
browser.  So, check for that condition, instead of saving, changing,
and then restoring the setting.

The function 'bottombars' has already done this.

There is no need to iterate through all the file names, as we already
know the length of the longest.  From this it's easy to calculate how
many names fit on a line.

Also rename some things to be more fitting.  And make sure that something
will be selected even when many files, including the selected one, have
disappeared.

When refreshing the screen (and thus the file list), use the prev_dir
mechanism to reselect the file that was selected before the refresh,
to prevent the selection from changing when files were added or deleted.

Also, when the selected name has disappeared, move the highlight one step
back, so that it is obvious that the selection has changed.  (Decrementing
'selected' will never make it negative, because selected == 0 means the
'..' entry, and every directory has a '..' entry, so it will be found.)

This fixes https://savannah.gnu.org/bugs/?47812

And make the function actually refresh the list.  Useful for when files
have been added or deleted since opening the browser.

Add a global variable, 'present_path', so that 'cwd_tab_completion()'
knows where the user is in the browser, so that it can try completions
against names in that directory instead of always against names in the
current working directory (where nano was invoked).

Simply move to the next filename first before starting to match.

Don't skip the end of the function: use break instead of return.

an operating directory is not the same as restricted mode.

(In restricted mode, the file browser is not available at all.)

We will need this again when one day we make a toggle between
jumping to a directory and searching for a filename fragment,
just like the ^T toggle that exists in the Search / Go-to-line
menus.  But for now, we don't need this.

functions that could be executed -- other than the line-edition ones,
which are executed under do_prompt().  So the latter won't return
unless either it was cancelled or an answer was given.  Also, if it
/had/ returned with a value bigger than zero, it tried to put back
the key sequence for do_gotolinecolumn_void(), which does not exist
in the MBROWSER menu, so this would not have done anything.
