- Update to version 2.6.3
* Build fixes for glibc 2.16 and Automake 1.12.
* apropos prints an error message and returns non-zero when it finds
no matches. (Regression introduced in 2.5.1.)
* The presence of a 64-bit GDBM database on the manpath no longer
causes a 32-bit man process to exit with a fatal error.
* apropos is much faster when run with many arguments.
* whatis may be given the full path to an executable as an argument,
in which case it will look up the base name of that executable in
the appropriate parts of the manpath.
* Translated manual pages are no longer displayed starting with a
spurious blank line.
* Fix double-free in mandb when encountering a symlink outside the
manual hierarchy, thanks to Peter Schiffer.
* Running 'man -w' (with a new --path alias) without a name now
prints the manpath, for compatibility with other man
implementations. The vim viewdoc plugin makes use of this.
* Fix a segfault when scanning links to empty pages.
* Once we've seen at least one record in a page's NAME section,
ignore any further records that don't include a whatis
description, as they tend to be noise.
* Ensure that the target of a symlink or .so chain is always recorded
as a real page.
* Read a user-specified configuration file even if HOME is unset.
* Fix failure to display manual pages in some encodings when
installed setuid.
* Wrap long table cells in man(1), fixing test failures with groff
1.21.
* If an explicit section is passed to man, then pages that match
that section exactly will be preferred over pages that only have
