Subject: Issue 4786: fee.fi = 0 was interpreted as as fee = 0 for undefined fee
X-Git-Tag: release/2.19.38-1~6^2~4
X-Git-Url: https://git.donarmstrong.com/?a=commitdiff_plain;h=36db2fa47f596e6e41a60473f837ea04ebfd7849;p=lilypond.git

Issue 4786: fee.fi = 0 was interpreted as as fee = 0 for undefined fee

If fee had been defined previously, the behavior became more sensible,
treating fee as an alist with a value of 0 for key fi.  This is now
always the case.
