in 6251644 the change to the makeflags sed also made it less specific, acting on lines matching "MAKEFLAGS" instead of "^#MAKEFLAGS". the change to the pacman color sed in 1bd9a35 once given the same correction only saves 1 character over the previous commit's more readable expression where "Color" appears twice, so it's reverted to that.
because the pattern ends with ".*" the "$" is useless. also made the sed for uncommenting "Colors" slightly shorter by using "/<pattern>$/s/^#//" instead of "s/^#<pattern>$/<pattern>/"
Change sed regex to '^#ParallelDownloads.*$' so it can handle lines like
#ParallelDownloads = 5
#ParallelDownloads = 8
#ParallelDownloads<any other value>
After enabling arch repos, need to download database files. Otherwise, calls to
`pacman -S` return errors that are suppressed by redirection to /dev/null.
Error Message:
```sh
warning: database file for 'extra' does not exist (use "-Sy" to download)
error: failed to prepare transcation (could not find database)
```
Fixes: https://github.com/LukeSmithxyz/LARBS/issues/393
1. We need them quotes (`"`) where they are specified in the `40-libinput.conf` file, but if you use `echo` and echo surround the output string itself with the double quotes (`"`), the ones inside it will get removed. fixed.
pretty lucky that I just happened to be a part of the convo in https://github.com/LukeSmithxyz/LARBS/issues/118 to get a notification & thus notice & try out 1d8b03595a - Xorg reported an error and couldn't launch i3, so here we are:D
2. (misc since it doesn't matter as much here but anyhow) `echo` shouldn't be used in any scripts anyway because it's unpredictable, and `printf` should be preferred (imo, anyway. Just mind that you there's no extra newline so if you need one/expected one from echo - add it yourself):
```sh
# unpredictable echo (with newline by default, though not always)
$ echo "omg larbs so kewl"
omg larbs so kewl
$
```
```sh
# predictable printf without a newline by default
$ printf "omg larbs so kewl"
omg larbs so kewl $
```
```sh
# predictable printf with a newline because you said so
$ printf "omg larbs so kewl\n"
omg larbs so kewl
$
```
take care!
