| | | | | | | | | | stdio buffers While here replace "SUSv[67]" with "POSIX Issue [67]" and update signal(3) to mention that pselect() and ppoll() are async signal safe like sigaction(2) already does. ok guenther
* Oops, getentropy() is an "extension interface", not a "base interface"matthew2014-07-181-2/+3
| | | | | Also, update the async signal safe list in signal(3) too (reminded by deraadt)

* make -column lists pretty again;jmc2011-09-031-37/+36
| | | | | | | | | | specifically, rewrite them to permit some markup in the column headers, and use "Ta" instead of literal tabs; mandoc does not currently match groff 100%, but a mandoc fix may be some time off, and we've gone enough releases with poorly formatting column lists. in some cases i have rewritten the lists as -tag, where -column made little sense.
* Do not attempt to silently continue text for the last column of tablesschwarze2010-02-251-5/+3
| | | | | | | | | | | | | generated by .Bl -column .It <tab> on following lines. This is a workaround; fixing it properly in a way compatible with our old groff would require .Xo support for .Bl -column phrases in mandoc(1), which is too much work right now just to fix exactly this one place in our tree. ok jmc@ This commit fixes the last issue i'm aware of which prevented building our whole tree with mandoc. Not all pages format nicely yet, but none kill the build any more.
