[PATCH 2 of 4] test-help: fix grep pattern for Windows

[timeless]

before some of my changes (e.g. stable),
[timeless at gcc2-power8 crew]$ hg help -k clone|grep debug
 debugapplystreamclonebundle  apply a stream clone bundle file
 debugcreatestreamclonebundle create a stream clone bundle file

but, basically, "debug" shouldn't appear unless you use --debug (in
which case, it should be listed) or are searching for "debug".

although, it looks like the test is checking the wrong flag, `-c`
(oops) -- i.e. it should test at least `-k`.
