In GNU Emacs 26.3 (build 1, x86_64-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
of 2020-05-17, modified by Debian built on x86-csail-01
I set bibtex-contline-indentation as a file variable, yeet it is ignored
by bibtex-mode.
I am not sure how file variables and minor modes interact, but it looks
like when the minor mode is fired, the local variables have not been
set yet.
Whatever the reason, bibtex-mode sets fill-prefix as a local variable
irrespective of the file variable bibtex-contline-indentation.
The fix for my case is simple: avoid setting fill-prefix as a local
variable in the minor mode, and just set it inside the
bibtex-fill-field-bounds function. A patch follows.
However, I don't know if this is a hint of some more general problem on
how bibtex-mode trets file variables.

This patch would make it impossible for people to alter fill-prefix
(from the mode hook, for instance), so I don't think this is the right
solution.
Looking at hack-local-variables/normal-mode, file-local variables are
set after the mode has been set up, so you can't have your mode set up
variables based on file-local variables. (If I'm wrong here, please
somebody correct me.)
So you can't usefully set
bibtex-entry-offset/bibtex-contline-indentation as file-local variables
without also setting fill-prefix that way, I think?

Can you please try the attached patch using hack-local-variables-hook?
This was partly inspired by the related comment
https://debbugs.gnu.org/cgi/bugreport.cgi?bug=21764#15
which had somehow escaped my attention. The issues mentioned in
this comment should likewise be fixed by the attached patch.

If I'm reading the patch correctly, it looks good to me -- it'll still
allow people to set fill-prefix from bibtex-mode-hook, and it fixes the
reported problem in these two bug reports. (I haven't tested the patch,
though, just read it.)

Installed as patch d9167d940ac9d0504cc38a044c7cba897c103eaf.
I am closing both bug#44618 and bug#44647.

Sorry for the delay, I have now managed to test the latest version of
bibtex.el which includes your patch, and it works for me. I made
various tests and I saw no problems.
Thanks
