bootstrap.el may fail behind a proxy

[donkopotamus]

What's wrong

In order to install straight.el boostrap.el:

• unconditionally clears straight-recipe-repositories; then
• calls a sequence of (straight-use-recipes ...)

If any of these repositories are blocked by a proxy (in my case nongnu-elpa on git.savannah.gnu.org) then the bootstrap fails without installing straight.

Could the addition of these repositories be gated somehow? For example I hacked in the following sort of check (I am not strong on lisp!)

(if (or (not (boundp 'straight-bootstrap-use-nongnu-elpa))
    straight-bootstrap-use-nongnu-elpa)
    (straight-use-recipes ...)
)

And then I set the following before the standard bootstrap snippet

(setq straight-bootstrap-use-nongnu-elpa nil)
(defvar bootstrap-version)
(let ((bootstrap-file ...
)

This successfully skipped that recipe repository. There is probably a far better way however.

One option to avoid forking straight.el is to use straight-recipe-overrides to set the URLs correctly or set them to a stub definition. However, you are correct that this is a missing feature. It should be possible to customize which recipe repositories are used by default.
