I love these and wish they were used more by command line applications. For instance in GCC, when your terminal supports them, compiler diagnostic flags are clickable and something like "warning: address of local variable ‘a’ returned [-Wreturn-local-addr]" can be clicked to open the GCC documentation for that flag.

This is a basic copy-paste and search function. I admit that your approach is fast but counter that it highlights a failure to make basic functions like copy-paste and search efficient and introduces a whole class of complexity into software design.

Edit: the same applies to diffs generated by /bin/diff. Most of the time, diff strings are unique enough to locate them by plain text searching.
