hifiasm: multi-file input syntax fix

[abueg]

I am sorry about the third pull request in like a week 😭

so I looked back again at the help from hifiasm and the syntax for multiple files for ONT/HiC is actually as such in the latest version:

Hi-C-partition:
    --h1 FILEs   file names of Hi-C R1  [r1_1.fq,r1_2.fq,...]
    --h2 FILEs   file names of Hi-C R2  [r2_1.fq,r2_2.fq,...]
  Ultra-Long-integration (beta):
    --ul FILEs   file names of Ultra-Long reads [r1.fq,r2.fq,...]

so I just edited the join command in the command-building part to delimit with a , instead of a space, does this look OK?

here is how the command builds when I tried this out:

so I put the single quotes back, and made a test that checks for the multi-input for UL, and the command built looks OK (the file paths are in single quotes), but the command reported in the logfile doesn't have the single quotes, is this OK since the paths are still getting passed properly to the program?

-ul seems to have quotes, for me this looks good. Can you explain where you don't see quotes?

[abueg]

ah, in the logfile output (the top code block) the paths aren't in quotes, though that is probably fine since hifiasm is reading the paths correctly?

Merci!
