31.1Srillig# In jobs mode, the shell commands for creating a target are written to a
41.1Srillig# temporary file first, which is then run by the shell.  In chains of
51.2Srillig# dependencies, these files would end up empty.  Since job.c 1.399 from
61.2Srillig# 2021-01-29, these empty files are no longer created.
