Improvements to path resolution in tlmgr and other scripts using kpathsea

[Daniel Nachun]

Hi Norbert,

I attached what I think is the right set of patches to change the usage of SELFAUTOPARENT to TEXMFROOT for the scripts which TeXLive itself maintains.  Please let me know if anything needs to be changed!

    Hi Daniel,

    I just commented on the PR.

    > 1) Homebrew tries to avoid carrying patches ourselves as much as possible.  We do not have dedicated maintainers for specific packages so it's not efficient or easy for us to maintain patches.  For that reason we try to find solutions that require minimal patching, or try to upstream patches when possible.

    Ok, we can look into this.

Ideally we'd be able to treat HOMEBREW_PREFIX/Cellar/texlive/58837 like /usr/ is on Debian, though that does not work at the moment for the reasons mentioned in my previous email.

    Ah yeah, forgot about this. So you cannot hardcode the path indeed. then
    your proposed way to patch tlmgr would be fine, but I am not sure about
    how we could integrate this into the main code base without breaking.
    There would be the need for some automatic detection in tlmgr.

    Makes it much easier to develop a Formula, definitely. 
    With only one TL package in Debian it would be rather simply to get
    everything going, and in particular no problem with config files.

    Well, I have linuxbrew installed (since I contribute on Formula for
    CafeOBJ), and will try if it works build the current TL formula using
    linuxbrew.

    Best
