To use astro(1) and scat(1) one has to create sky/here and download various catalogue files as detailed in sky/README. This change marks those files as ignored by git so they don't clutter its status messages.

TERM_PROGRAM is the customary way to identify which kind of terminal emulator program one uses on macOS. This change sets TERM_PROGRAM to termprog since both variables are used for the same purpose.

read(3) sometimes errors with EINTR on macOS over slow connections. 9pfuse(1) now retries read(3) instead of sysfatal(3)ing.

Fixes #81.

as the old grody way doesn't work any more on FreeBSD-10 and later.

rc on amd64 stores ulimit values as 32-bit int, but the limits on OpenBSD amd64 can exceed 2^31, so "ulimit -a" shows some values as negative. This is a problem when I want to increase my ulimit but the hard ulimit values are printed as negative.

Fixes #6. Change-Id: Id9950f59c7970575866a7c22a69bfbf3a271f2bb

Before, executing Get in a file rewound the window offset and selection to the start of the file. After this CL, Get preserves the window offset and selection, where preserve is defined as "the same line number and rune offset within the line". So if the window started at line 10 before and the selection was line 13 chars 5-7, then that will still be true after Get, provided the new content is large enough. This should help the common situation of plumbing a compiler error, realizing the window is out of date, clicking Get, and then losing the positioning from the plumb operation.

This PR adds additional files to update /usr/local/plan9 references for packaging.

Thanks to Lorenzo Beretta for noticing.

Fixes #114.

Since macOS 10.13, opening the /dev/ptyXX files always return ENOENT. Consequently, we changed getpts to use openpty to open a pseudoterminal, like on Linux and OpenBSD. Fixes #90. Fixes #110.
