Even though a user would never type ^J to start a new line, accept it
as a synonym of <Enter> (^M) in a bracketed paste, because apparently
bash accepts it as a synonym too.
This works around https://savannah.gnu.org/bugs/?58010.
The old address has become invalid, and probably does not have enough
room for the write, thus causing a crash.
This fixes https://savannah.gnu.org/bugs/?57858.
Bug existed since commit 8625609c from two days ago.
Not doing it characterwise saves a reallocation, a memmove(), several
checks, and an update_undo() for each character over one.
This has been tested by temporarily setting 'bracketed_paste = FALSE'
instead of 'bracketed_paste = TRUE' in convert_sequence() in winio.c,
and then pasting stuff into nano.
And before the buffer size is adjusted, so that the add_undo()
doesn't need to correct the stored former size of the buffer.
This will allow the injection of multiple characters at once,
in the next commit.
Using straightforward comparisons is clearer and faster and shorter.
Again, note that this does not filter out 0x7F (DEL). But that is
okay, as that code will never be returned from get_kbinput().
The few calls of the injection routines that had 'filtering' set to
TRUE have already filtered out ASCII control codes earlier on. And
in the case of injecting a completion, this completion only contains
word-forming characters -- and if the user somehow added a control
code to the word-forming characters, then nano should NOT filter it
out, so in fact that setting of 'filtering' to TRUE was mistaken.
Note that this filtering did not filter out 0x7F (DEL). But that is
fine: it should not occur in the input stream at that point anyway,
as it gets translated to either KEY_DC or KEY_BACKSPACE earlier in
the keyboard parsing routines.
When at startup the user presses Cancel at the "open anyway?" prompt,
cancel the whole startup: quit. But when the user answers No, just
skip the file and continue starting up.
The 'prev' and 'next' links get assigned to immediately after the
call of copy_node(). And anyway, it does not make sense to link
a copied node to the predecessor and successor of its original.
Also slightly regroup some lines.
Also, the disabling of the keyboard interrupt (SIGINT) must happen
after that initialization call, otherwise ^C will still do nothing
after returning from suspension (when nano is built against Slang).
This fixes https://savannah.gnu.org/bugs/?57656.
Bug existed since version 2.2.0, commit daaf468c.
The tiny version is oblivious of bracketed pastes, as it serves no
purpose: in the tiny version there is no auto-indent nor undo nor
tabs-to-spaces conversion.
Any modifier keys that are needed to start the execution of a macro
(or of a string bind) should not affect the interpretation of the
keystrokes that are contained within the macro or the string.
This fixes https://savannah.gnu.org/bugs/?57660.
Bug existed since macros were introduced, in version 2.9.0.
As long as the user does not define any Sh-M-X bindings in their nanorc,
<Shift> and <CapsLock> will not have any effect on <Alt+letter> combos.
But as soon as any Sh-M-X combination is bound, <Shift+Alt+letter> will
be seen as different from the unshifted keystroke.
This kind of fulfills https://savannah.gnu.org/bugs/?54659.
