Merge pull request #41 from orbea/gentoo

Fix the build on gentoo.

On gentoo the build also requires -ltinfow which is exposed
by the ncursesw.pc pkgconfig file.

More standard install

build: Use FHS and GNU paths for MANDIR

The FHS path for MANDIR is /usr/share/man.

https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch04s11.html#usrsharemanManualPages

While GNU directory variables show MANDIR to be DATADIR/man

https://www.gnu.org/prep/standards/html_node/Directory-Variables.html

build: Explicitly set variables

build: Use standard install variables

This removes DESTDIR from both BINDIR and MANDIR and adds it directly
to the intall and uninstall rules.

This also moves 'man1' directly to the rules as it should not be
configurable by the user.

And lastly this removes the non-standard and now useless MANPREFIX.

Version 1.0.1.

Correctly handle CJK/double width characters.

Fix memory errors when browsing empty directories.

Correctly handle CJK/double width characters.

Some CJK characters take more than more column on the terminal, so should use
wcswidth to calculate the screen width.  Also fixed potential buffer overflow
in calls to swprintf.

Prefer VISUAL to EDITOR

VISUAL is useed on many systems these days without EDITOR being set, see
the manual pages for various shells or other documentation.

This patch makes rover respect VISUAL being set in the environment and
prefer it to EDITOR.
