[1/1] */*: egrep -> grep -E, fgrep -> grep -F

  Newer versions of grep (after grep 3.7, not inclusive) will warn on
'egrep' and 'fgrep' invocations.

Convert usages within the tree to their expanded non-aliased counterparts
to avoid irritating warnings during ./configure and the test suite.

> [PATCH 1/1] */*: egrep -> grep -E, fgrep -> grep -F

I do not see previous occurrences of */* in the subject line, but I
assume it's ok. In the Linux kernel folks tend to use `treewide:`.
I see that there is exactly one glibc commit using `treewide:`.

Confirmed: https://git.savannah.gnu.org/cgit/grep.git/commit/?id=a9515624709865d480e3142fd959bccd1c9372d1
("egrep, fgrep: now obsolete")

```
for i in **/configure.ac; do ~/projects/autoconf-2.69/bin/autoconf -I.  $i > ${i/.ac}; done
```
does not update any file, so this patch correctly updates all relevant configure files.

For this patch I suggest using the prefix "grep:". Though it's not a big 
deal; on the rare occasions I make a treewide commit I typically don't 
use a prefix.

Other than the commit-line prefix, the patch looks fine. Thanks.

In the next GNU grep release we also plan to warn about REs like '\a' 
that use undocumented escape sequences, where POSIX explicitly says the 
interpretation is undefined, the GNU documentation is silent, and GNU 
grep historically has been flaky because the glibc regex code is flaky 
(unfortunately nobody these days has much time to fix glibc regex). I 
expect and hope that these new warnings don't affect glibc builds, 
though I haven't checked for this.

OK.

BTW: Do the modified files need the one-line description
"Copyright The GNU Toolchain Authors." from
https://sourceware.org/glibc/wiki/Contribution%20checklist#Update_copyright_information ?

Aha.

Not for this change, no, as the change is trivial and you're 
contributing by assigning copyright not via DCO.

I see that the wording in that URL was confusing: "those changes do not 
have their copyright assigned to the FSF (contribution via DCO)" sounded 
like it was talking about changes *not* contributed via DCO, whereas the 
wording was intended to refer to changes that *are* covered by DCO. I 
changed the wording as follows to try to clarify things.
