bug#23179: 25.0.92; Restore `M-,' to continue etags search

[Anders Lindgren]

Hi!

 

Searching through all of those, by opening each one in Emacs in sequence, with re-search-forward, is surely slower that using Grep.

I just tried your `tags-find-regexp' on Windows, and it failed miserably. It appears to be hanging, but after setting `debug-on-quit' to t and pressing C-g, it always breaks when running an external "grep" command. My conclusion is that starting "grep" on windows is very, very slow compared to opening a temporary buffer and doing re-search-forward.
