[PATCH] am: unify definition of --keep-cr and --no-keep-cr

["René Scharfe" <l.s.r@web.de>]

The options --keep-cr and --no-keep-cr set the variable keep_cr to 1 and
0, respectively.  We don't usually define the negative variant
explicitly.  The extra help text only tells users that the option
overrules the config option am.keepcr, which conforms to convention.

So allow --keep-cr to be negated and drop the now redundant definition
of --no-keep-cr for consistency.
