Suppose we search for a git conflict marker '<<<<<<< HEAD' using
the command '/^<<<'. Using 'n' to go to the next match finds
'<<<' on the current line, apparently ignoring the '^' anchor.
Set a flag in the compiled regular expression to indicate that the
start of the string should not be considered a beginning-of-line
anchor. An exception has to be made when the search starts from
the beginning of the file. Make a similar change for end-of-line
anchors.
This doesn't affect a default build with VI_REGEX_SEARCH disabled.
When it's enabled:
