New Revision: 326526
URL: https://svnweb.freebsd.org/changeset/base/326526
Log:
In case man(1) found a catpage to display skip looking ".so" which is manpage
only.
In case we are trying to read a catpage, the manpage variable is not defined.
It results in the "cattool" having no arguments.
In case the catpage is compressed, the cattool used is "zcat" which dies if
the
standard input is a terminal, meaning the function calling it is exiting as if
there were no ".so"
In case the catpage is uncompressed, the cattool used is "zcat -f" which waits
reading standard input, making the man(1) command hang.
