bash-2.04.
In .spec file, there is a (very ugly written) code to remove
^H from bash-xx.yy/doc/* files. The only files that have this ^H
is -- article.txt, *.0 (preformatted manual pages) and bashref.dvi (yes,
binary file).
But -- when building as non-root, this whole code will complain
(and fail) on file texinfo.tex (!) while trying to remove that
(never existed here) ^H, since texinfo.tex is read-only.

Moreother, *.0 files (I think) should not be installed at all, since
this is a man pages (that is installed anyway).
