bug#18985: 24.3; cperl-mode misindents hash keys that start with an auto-quoted keyword |

cperl-mode has a nasty bug in M-x indent-region, if you write this to a
file:
my %x = (
for_me => "cookie",
);
And indent it you end up with:
my %x = (
for _me => "cookie",
);
Note the space between the "for" and "_me", the indenter falsely thought
that "for" was a keyword and suffixed it with a space, changing the
semantics of the code.
The same issue happens with some other keywords, e.g. "if" and "until",
but interestingly not "unless".
