# Due to a bug in certain Bash versions, any external process launched
# inside $PROMPT_COMMAND will be reported by `jobs` as a background job:
#
# [1] 42135 Done /bin/echo
#
# This is a workaround - we run `jobs` once to clear out any completed jobs
# first, and then we run it again and count the number of jobs.

# Evaluate the number of jobs before running the preserved prompt command, so that tools
# like z/autojump, which background certain jobs, do not cause spurious background jobs
