Hi!

The idea makes sense, but perhaps we shouldn't add one more way of doing 
this and just copy what grep-read-regexp does. Meaning, define a 
project-specific var and then use it. We could use 'grep-regexp-history 
there too, as another alternative.

But having a var called project-regexp-history seems more powerful, and 
even no less powerful than your suggested approach, because one can 
always turn that variable into a defalias, if they so wish.

(I often use regexps when searching in project, but this change doesn't 
seem problematic for this usage either.)
