The documentation of grep-files-aliases says:
*Alist for the FILES argument to `lgrep' and `rgrep'.
Certain aliases in that list do not work with lgrep.
For example, `cc' works fine with rgrep, but fails with lgrep with the
following recipe:
emacs -Q
M-x lgrep
Search for: main
in files: cc
In directory: ~/devel/emacs/trunk/src/
Result:
-*- mode: grep; default-directory: "~/devel/emacs/trunk/src/" -*-

Why do you think this is a "failure"? There indeed are no files
matching these widlcards in the Emacs's src directory.
I guess you are right. I compared it to rgrep where the result is
`Grep:exit [no match]' and the mode line says `Grep finished with no
matches found'. Whereas with lgrep you get an `abnormal exit' from grep
even if there are matches to some of the wild cards. This example was
contrived. I noticed this at work in a tree where there were .CC and
.cpp files present, but grep still exited abnormally.
There is no failure in Emacs. I'm closing this. Thanks.
