[PATCH] doc: clean up doc/Makefile.am

[Jim Meyering]

FYI, I noticed commands going by, in spite of my
building with the default V=0, looked at doc/Makefile.am
and found several things to fix/improve:

Subject: [PATCH] doc: clean up doc/Makefile.am

* doc/Makefile.am (egrep.1 fgrep.1): Generate robustly, i.e.,
do not redirect directly to address@hidden
Use $(AM_V_GEN).
Do not distribute intermediate files like fgrep.man and egrep.man.
Likewise, do not use them to generate their %.1 images.
Instead, generate the .1 files directly.
