[PATCH] help.c: mark a file-local function static

[Ramsay Jones <ramsay@ramsay1.demon.co.uk>]

Commit 4f671d74 ("help: respect new common command grouping",
18-05-2015) adds the 'cmd_group_cmp' funtion as an external
symbol.

Noticed by sparse. ("'cmd_group_cmp' was not declared. Should it
be static?")

Hi Sebastien,

If you need to re-roll the patches in your 'sg/help-group' branch,
could you please squash this into the relevant patch (commit 4f671d74).

Thanks!

ATB,
Ramsay Jones
