Description

Steps to replicate the issue (include links if applicable):

python pwb.py touch -family:wikisource -start:A 
(-lang cs)

What happens?:

ERROR: Unable to execute script because no generator was defined.
Use -help for further information.

What should have happened instead?:

Page [[A. R.]] saved
Page [[ABGB]] saved
Page [[A co?]] saved
Page [[A co?/A co básník]] saved

When I use python pwb.py touch -family:wikisource -prefixindex:A everything works as excepted.
But prefixindex is not suitable for pages on the beginning and the end of pagelist
Software version (on Special:Version page; skip for WMF-hosted wikis like Wikipedia):

I was able to reproduce this issue and investigated the regression locally. Since the task is already being worked on, I'll unassign myself. Please let me know if any additional testing would be helpful.

@Zaidusyy: review of my change would be helpful
@JAnD: Because this is a important regression introduced with 11.3 I will publish a 11.4.1 stable release shortely after review.
