This fix is required for the raspherry pi 3 with glibc 2.27, otherwise the kernel panics in initrd with: ``` <<< NixOS Stage 1 >>> loading module dm_mod... running udev... kbd_mode: KDSKBMODE: Inappropriate ioctl for device Gstarting device mapper and LVM...

This adds some initial values for .dir-locals.el. Mainly this is useful for using bug-reference-mode. So if you have bug-reference-mode enabled - > M-x bug-reference-mode You will see as clickable text like this: Fixes #15 (#12) Closed NixOS#1252 issue #1

The sed expression actually caused an error on hydra: ``` sed: -e expression #1, char 18: Invalid collation character ``` It seems to build fine without it however.

On my systems there is a path in the fonts list that looks like
/nix/store/<hash>-<font>.ttf. The previous code assumed that every font path
contains at least one more slash which isn't the case here.
The code matched on the / after the $out path of the derivation:
/nix/store/<hash>-<name>/share/X11/fonts/...
^
That slash only exists if the font lives in a subdirectory, which
isn't strictly required. In my case I've a few font files that are
located at /nix/store/<hash>-<name>.ttf and are assembled into a
folder as symlinks. (See example below)
Any attempt at calling realpath(3) on them (potentially recursively)
will result in the single file entry in the store being returned.
Whenever that font is being loaded flatpak segfaulted like so:
```
(gdb) bt
#0 0x00005583b3673763 in get_nix_closure ()
#1 0x00005583b3673711 in get_nix_closure ()

#3 0x00005583b36749a8 in add_font_path_args ()
#4 0x00005583b367b3f4 in flatpak_run_app ()
#5 0x00005583b35e4f08 in flatpak_builtin_run ()
#6 0x00005583b35a5970 in main ()
(gdb) x/5i $rip
=> 0x5583b3673763 <get_nix_closure+307>: movb $0x0,(%rax)
0x5583b3673766 <get_nix_closure+310>: call 0x5583b35a46a0 <g_hash_table_add@plt>
0x5583b367376b <get_nix_closure+315>: jmp 0x5583b3673699 <get_nix_closure+105>
0x5583b3673770 <get_nix_closure+320>: xor %edi,%edi
0x5583b3673772 <get_nix_closure+322>: lea 0x30475(%rip),%rsi # 0x5583b36a3bee
(gdb) x/s $rsi
0x5583e92d2180: "/nix/store/<hash>-A.ttf"
(gdb) print $rax
$1 = 0
```
RAX pointing to 0 here corresponds to the pointer `p` in the source
code. So the code attempted to dereference a null pointer as no further
slash (the return value of strchr(3)) could be found.
The modification in this commit ensures that we check for `p != 0` so
we don't run into this situation again.
Adding the path to the closure will still be done, even if no further
slash can be found, as that still points to a valid store path.
----
Nix code for custom fonts:
```nix
let
files = [
./A.ttf
./B.ttf
];
in
runCommandNoCC "custom-fonts" {} ''
mkdir -p $out/share/fonts/truetype
cd $out/share/fonts/truetype
${ lib.concatStringsSep "\n" (map (file: "ln -s ${file} ${baseNameOf file}") files)}
''
```
