[hackers] [slock][PATCH] Reset color to INIT on Escape key press
This is so people who have the INIT color set to black but the FAILURE
color set to something else can still have their monitor black out after
failing to unlock, without having to unlock and lock again.
Also makes sense because pushing Esc isn't really a failure, but a
purposefully aborted unlock attempt, so the background shouldn't be set
to FAILURE.
(Note: let me know if you prefer to pull from Github, I'm new to the
list.)

Re: [hackers] [sbase][PATCH] grep: remove = flag from readme
Perhaps it could be noted. But it fails with both musl and glibc. I think we need new regex engine, perhaps adapted from musl, that supports NUL bytes and UTF-8 transparently. maandree On Sun, 3 Apr 2016 22:30:45 +0200 FRIGN wrote: > On Wed, 30 Mar 2016 19:01:16 +0200 > Mattias Andrée wrote: > > Hey Mattias, > > > $ echo äö | ./grep [å] > > äö > > > > This is not want one expects from > > a program that supports UTF-8. > > I assume the proper way here would be to add a note on > the manpage that this highly depends on the libc you are > using (and esp. the Regex engine). > > Cheers > > FRIGN > pgpBloNgHUxcG.pgp Description: OpenPGP digital signature

Remove line-breaks from Makefile
Even though I like line-length limits, it imposed a useless limitation
on the console output, given the line input is variable.

Makefile improvements
- be verbose by default: don't hide the executed commands.
- no need to make clean on make dist, but make sure to have a clean
directory.
- define 2ff in ${SCRIPTS}.
- make dist: gzip directly, don't store intermediate step (faster for make
dist
on floppies).
- don't cd into directories, just loop each file.
