Benno Schulenberg a5b3f00d78 chars: make comparing multibyte strings twice as fast
Instead of parsing every multibyte character twice, first with
parse_mbchar() and then with mbtowc(), just let mbtowc() do all
the work.  This makes searching for a fixed string twice as fast.

This also gets rid of four variables and lots of memory allocations.
(And, more importantly: it stops nano messing up the internal state
of the multibyte-to-wide character conversion, and thus would make
the calls to mbtowc_reset() superfluous.)

Benno Schulenberg fbb6208d15 browser, files: use full path in error message when in confined mode

Benno Schulenberg f9fe9a7d57 backups: take an unlikely condition into account
Between the first stat (that sets 'realexists') and the second stat
(directly after), the file might have disappeared, which would mean
that current_stat would be NULL.  Prevent dereferencing this further
down.

Benno Schulenberg e65352bc8a files: when writing a lockfile fails, continue loading the file
Only when the user decides not to override an existing lockfile should
loading the corresponding file be skipped.  Any failure to write the
lockfile should be ignored -- the file itself should be loaded anyway.

Benno Schulenberg c9d1936f02 files: don't reuse a variable that may have been modified by dirname()
The variable 'namecopy' has been passed to dirname(), so it is likely
to have been changed when it contains a slash.  So, use a new variable
instead.  Also, free the result of display_string().

Benno Schulenberg faf5227bc5 files: remove a superfluous condition, and do not ignore a "No"
Having just opened a fresh buffer, 'openfile->next' will never be NULL,
because the list is circular.

Second, when compiled with --disable-nultibuffer, and deciding not to
override an existing lock, the 'return FALSE' should *not* be skipped,
because otherwise the named file will be opened after all.

This fixes an unreported bug.

just go and read the next key.

Benno Schulenberg 2535f51e01 statusbar: prevent error messages from overwriting each other
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.

Benno Schulenberg 58404e4ba2 browser: keep the highlight in the same spot or column, when possible
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.
