Lists on the man pages don't seem to be able to have a single entry, because sowing requires you to start lists with "+" and end them with "-", requiring at least two entries.
This leads to ugly-looking indentation for man pages for functions with a single input or output parameter, e.g. https://www.mcs.anl.gov/petsc/petsc-dev/docs/manualpages/DMSTAG/DMStagVecGetArrayDOF.html I think that this can be remedied with a small change to sowing (doctext), to interpret a lone '-' as opening a list (and then closing it after one entry): https://bitbucket.org/psanan/sowing/commits/780ea53824388e8c6089ae2d6210332c63935edb (Posting this here since I'm not sure how closely the bitbucket.org/petsc/pkg-sowing repository is monitored)
