Add option to remove delay on scripting errors #319
Description
I'm using elinks to render HTML messages in mutt. Recently, I noticed a delay when opening certain HTML messages. I traced it back to elinks, probably this line:
elinks/src/scripting/scripting.c
Line 47 in d501d76
I also use python hooks for a different purpose, so they simply return the argument in this case, but this triggers the delay.
You can verify like so:
$ rm -rf ~/.config/elinks
# Create file in "wrong" encoding
$ echo '<!DOCTYPE html><html><head><meta charset="utf-8"></head><body>Ö</body></html>' > test.html
$ iconv -f utf8 -t ISO8859-15 test.html > test-iso.html
$ touch .config/elinks/hooks.py
# This is quick
$ time elinks -dump test-iso.html
elinks -dump test-iso.html 0.02s user 0.01s system 100% cpu 0.032 total
$ mkdir -p ~/.config/elinks && echo 'def pre_format_html_hook(url, html):\n return html' > ~/.config/elinks/hooks.py
# This is slow
$ time elinks -dump test-iso.html
ELinks: [Python 3.12.5 error] UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd6 in position 62: invalid continuation byte
╓
elinks -dump test-iso.html 0.03s user 0.01s system 1% cpu 3.039 totalI suppose the intent is that the error is loud so that the user notices. However, in this case, I'd rather have it fail silently and see a few corrupt characters. Or bail out entirely and return a non-zero exit code, then I would have found the issue sooner.

(As a workaround I now pipe the file through iconv first to make sure it's always utf8.)
