In the preceding commit, open_buffer() was changed so that it gets
told whether to load into a new buffer or not, so it is no longer
needed to convey this information through a flag.

2018-02-27 13:34:32 +01:00
01457ae3d3
input: handle the implant() function separately, as it is special
...
The implant() function itself cannot be bound to anything, so it
is not in the linked list of functions -- trying to find it would
lead to a NULL pointer, and thus to a segfault.
This fixes https://savannah.gnu.org/bugs/?53233 .

54103d8ed1
tweaks: elide another variable, to call a function less often
...
Instead of always calling sctofunc(), it is now only called when
in view mode OR when (after the keystroke's function has been run)
no need for a refresh has been established yet.

28933cf572
tweaks: remove two superfluous checks, and restrict two others
...
When 'refresh_needed' is already TRUE, there is no need any more
to check whether it should be set.
[Those first two calls are leftovers from before the time that
reset_multis() morphed into check_the_multis().]

input: don't stop prepending when the user adds text via a shortcut

In this way a single keystroke can produce a fragment of text or a
