This is a bug report for perl from Keith.S.Thompson@gmail.com,
generated with the help of perlbug 1.39 running under perl 5.14.2.
-----------------------------------------------------------------
I see this with Perl 5.14.2 under Ubuntu 12.04 beta2, and with
v5.15.9-134-g8aed2c6 built from the git sources, branch "blead".
"perldoc perlre" says:
m Treat string as multiple lines. That is, change "^" and "$"
from matching the start or end of the string to matching the
start or end of any line anywhere within the string.
But "$" (without /m) doesn't just match the end of the string; it
matches either the end of the string or just before a trailing newline.
I can't think of a non-clumsy way to word this.
