grep.c: extract show_line_header()
The grep code invokes show_line() to display the contents of a matched
or context line in its output. Part of this execution is to print a line
header that includes information such as the kind, the line- and
column-number and etc. of that match.
To prepare for the addition of an option to print only the matching
component(s) of a non-context line, we must prepare for the possibility
that a single line may contain multiple matching parts, and thus will
need multiple headers printed for a single line.
Extracting show_line_header allows us to do just that. In the subsequent
commit, it will be used within the colorization loop to print out only
the matching parts of a line, optionally with LFs delimiting
sub-matches.
