Improve the help displayed if the user presses an inactive key by only
listing active keys and printing specific messages for some keys. Also
disable search if there's only a single hunk.

Phillip Wood (3):
  add -p: only display help for active keys
  add -p: Only bind search key if there's more than one hunk
  add -p: improve error messages

If the user presses a key that add -p wasn't expecting then it prints
a list of key bindings. Although the prompt only lists the active
bindings the help was printed for all bindings.  Fix this by using the
list of keys in the prompt to filter the help. Note that the list of
keys was already passed to help_patch_cmd() by the caller so there is
no change needed to the call site.

If there is only a single hunk then disable searching as there is
nothing to search for. Also print a specific error message if the user
tries to search with '/' when there's only a single hunk rather than
just listing the key bindings.

If the user presses a key that isn't currently active then explain why
it isn't active rather than just listing all the keys. It already did
this for some keys, this patch does the same for the those that
weren't already handled.

Fix a regression in 88f6ffc1c2 ("add -p: only bind search key if

2.17.0-rc*, but not 2.16.0.

code that was expecting its $1, the $1 variable would always become
undef.

completely broke, on git.git:

tests for this, but looking over t3701-add-interactive.sh it seems
doable. Phillip: Maybe something you'd be interested in?

Of course I just noticed the grammar errors in the commit message
after sending. Here's a v2 with that fixed, also genreated the patch
with -U6 to make it clear what's going on.

Good catch, I could have sworn I'd tested my patch but I obviously 
didn't notice the warning (I've got interactive.singlekey set so it 
prints the warning and then prompts as it always has done). Calling it 
completely broken is perhaps a little harsh as it does work if you enter 
the regex again and with interactive.singlekey set you only have to 
enter the regex once.

Thanks for fixing it

To clarify by "completely broken" I mean the "/" feature itself, but
yeah, you can still search by regex since we just so happen to have the
fallback codepath intended to catch "/" without an accompanying string,
which'll kick in and ask you for the regex since $1 will be undef at
that point, and will thus coerce stringwise to "".

Ah.  That "unless ... { }" thing is what was inserted recently, and
the patch is an obvious fix once the problem is pointed out.  Thanks
for a careful reading.

It makes me wonder what the original author, who already captured $1
in $regex, was thinking when he wrote the comparison with $1 there,
but that is OK---ithappend long time ago in early 2009.

Will apply.  Thanks.
