The following works without the caret (^) specifying beginning of line; with
the caret, it doesn't match the input (which starts in column 1):

program:	perl -ne 'if (/^\w:/) { print; }'
on input:	nope:
gives result:	<nothing>
expected result: nope:
hypothesis:	the caret(^) specifying beginning of line is messing up the
		regular expression matching
version:	This is perl, version 3.0 ... Patch level: 44
