$line-template - Command line regular expression search string
$line-template "string"; Default is ""
$line-template defines a regular expression search string used to identify a line number in the grep(3) and compile(3) buffers. The format of the string is the same as magic mode search strings (see search-forward(2)).
The line number may be considered to contain any numeric number, thus $line-template is defined as:
set-variable $line-template "[0-9]+"
This correctly identifies "45" in the following *grep* output example:
foo.c: 45: printf("hello world\n") ;
