 * gnu/packages/tex.scm (texlive-xfithen)[propagated-inputs]:
   Readd propagation of `texlive-ifmtarg` to fix usage of package.

Change-Id: I9e5e3cfa0fad3dc9fd3b4950eedf7443b254d2f1
---
This was removed as a "spurious" propagated input by the
texlive-team-next changes, but in my usage it was not spurious and the
package propagation is needed to use `xifthen` correctly.

This is a limitation in TeX Live, not Guix's, package definitions. The
dependency is not reported in their "texlive.tlpdb" file.

Note there are hundreds of such issues. We cannot realistically fix them
manually ; for example this change would need to be tested every time
Guix TeX packages are updated.

I suggest to use collections of packages to avoid messing too much with
individual dependencies, and possibly report those missing dependencies
to the TeX Live project.

I don't know what Nix does. However, considering the sheer number of
packages involved, I don't believe in the sustainability of anything
even remotely manual.

Now let's suppose we solve this. E.g., the importer greps through ".ins"
or ".dtx" files to identify and declare a list of dependencies. Then
we'll face another, greater, issue: it will be no longer possible to
build TeX Live packages because of the dependencies loops we will have
just introduced. Let me insist of the fact that I'm not talking about an
hypothetical problem: I encountered it when I started to package the
missing TeX Live bits a few months ago.

If there's no solution, then there's no problem. ;)

The software works; the burden in on the user who wants to optimize
their TeX Live installation. I think this is a reasonable, and common,
expectation. I don't think the TeX Live installer takes a different
approach. On a different context, compare a user installing a full blown
DE, such as Gnome, to another one who picks a window manager, a file
manager, etc., and needs to glue these parts together to make them
behave as a coherent environment.

As a data point, I have a 20-ish TeX Live packages from latexetra
collection explicitly installed from my manifest as required
dependencies. This list hardly ever increases or changes, so this is
acceptable, at least for me.

Sorry for being pessimistic. Maybe Someone™ will find an unexpected
solution. Meanwhile, adding manually dependencies is, IMO, a no go.

Is there no way to declare that a package auto-generated from TeX Live 
should be "patched" in some way (in this case, to include the 
dependency)? I'm aware that Nix does something like this for their 
various package sets. Perhaps this would be more sustainable than a 
fully-manual process.

Unfortunately this particular package only appears in an unopinionated 
collection in latexextra, which is very heavy for something that I have 
to put in my manifest just to fix a dependency issue.

I'll look into getting the dependency registered on TL, but it's worth 
noting that they also don't want the responsibility of dependency 
tracking. They also don't recommend that package authors bother to put 
dependency information in their packages.[0] I'm conscious that this is 
a complex burden, but ideally *someone* would take it on so that the 
software works.

Best,

Isaac
