piegames 68927918d0 treewide: Fix indentation in strings
The indentation stripping semantics of strings are fairly bad and have a
few gotchas where the resulting string has not the intended indentation.
This commit fixes most if not all such instances in Nixpkgs.

I tried to strive a balance between keeping the diff small and
reformatting/refactoring the code to look better. In general,
reformatting should be left to Nixfmt.

Note that this causes a lot of rebuilds by design. All changes need to
be thoroughly vetted and reviewed for correctness. There is no automatic
way to prove correctness.

List of files to fix generated by running
https://gerrit.lix.systems/c/lix/+/2092 on Nixpkgs and looking at the
warnings.

longDescription = ''
GNU libextractor is a library used to extract meta-data from files
of arbitrary type. It is designed to use helper-libraries to perform
the actual extraction, and to be trivially extendable by linking
against external extractors for additional file types.
The goal is to provide developers of file-sharing networks or
WWW-indexing bots with a universal library to obtain simple keywords
to match against queries. libextractor contains a shell-command
extract that, similar to the well-known file command, can extract
meta-data from a file an print the results to stdout.
Currently, libextractor supports the following formats: HTML, PDF,
PS, OLE2 (DOC, XLS, PPT), OpenOffice (sxw), StarOffice (sdw), DVI,
MAN, FLAC, MP3 (ID3v1 and ID3v2), NSF(E) (NES music), SID (C64
music), OGG, WAV, EXIV2, JPEG, GIF, PNG, TIFF, DEB, RPM, TAR(.GZ),
ZIP, ELF, S3M (Scream Tracker 3), XM (eXtended Module), IT (Impulse
Tracker), FLV, REAL, RIFF (AVI), MPEG, QT and ASF. Also, various
additional MIME types are detected.
