Wrestling with &errorformat and ISO-8601 timestamps

I like to run Python unit tests using asyncrun.vim[*] and look at the
results in the quickfix window. One thing that annoys me is that when
the output contains assertion failures involving ISO-8601 timestamps
like this one:

E AssertionError: assert 'GitLab proje...tion: 42s\n' == 'GitLab proje...ob created:\n'
E GitLab project: owner/project
E - Job created: tbd
E + Job created: 2020-09-16T06:16:49.180Z
E + Job started: 2020-09-16T06:16:51.066Z
E + Job finished: not yet
E + Job duration: 42s

tests.py:346: AssertionError

Vim thinks there's an error on line 16 of a file named
"E + Job created: 2020-09-16T06"

How can I tell Vim that, as a Linux user, I don't believe in file names
with spaces in them? Or, as a compromise with Windows users, that file
names with multiple sequential spaces are _extremely_ unlikely?

My &errorformat is set as follows in my .vimrc:

set errorformat&
set errorformat-=%f(%l):%m
set errorformat+=E\ %#File\ \"%f\"\\,\ line\ %l%.%#
set errorformat+=File\ \"%f\"\\,\ line\ %l\\,%#%m

The help says %f pays attention to &isfname, which I haven't tweaked
much:

set isfname-=\=

and it does not include a space AFAICT.

Please help, vim_use@, you're my only hope!


[*] I have this set of plugins[+] that figure out the name of the unit
test that my cursor is inside, so I can press Ctrl+F9 and run that
single test in isolation, in the background, with my statusline
changing color to indicate test running/success/failed, with
quickfix opening automatically in case of failure. Ctrl+Shift+F9
reruns the last test so I can quickly fix the code and see if that
helped without navigating back to the test. Life would be utter
bliss except for this one small annoyance.

retrospect, putting Linux on my primary computer to help enforce that was
likely a valuable career decision.
