[PATCH 0/4] add -p: Term::ReadKey and more

[Thomas Rast <trast@student.ethz.ch>]

I added some more patches. 3/4 is the previous version, with code
added to make / work (it just prompts for a regex) and a configuration
variable added for Junio:

I decided to disable it by default since it is an inconsistency
between add -i and add -p for users of both, so if you want this
feature, make sure to enable interactive.readkey.  (I don't mind the
inconsistency as I never use 'add -i'.)

I also removed the stray %control_chars from back when my draft
versions used raw instead of cbreak mode, and consequently had to test
for Ctrl-C themselves.


Finally, the first two patches fix small problems I saw while looking
over the code, and 4/4 changes the color of error messages caused by
keyboard input to color.interactive.help, lest they drown in the hunk
that is automatically redisplayed.


Thomas Rast (4):
  add -p: change prompt separator for 'g'
  add -p: trap Ctrl-D in 'goto' mode
  add -p: prompt for single characters
  add -p: print errors in help colors
