[bug #62923] Broken aliases in PDF font description file

[anonymous]

Follow-up Comment #2, bug #62923 (project groff):

Thank you for fixing it! I applied the fix you provided and it works but I
noticed that one thing is still broken: if you add an alias with name
radicalex to sqrtex in XITSMR, the radicalex is rendered on the same position
as sqrt (in groff_out there's no h command after Csqrt):


.special XITSMR
.EQ
sqrt x
.EN


It somehow gets fixed if I add this line at the top:


.char \[radicalex] \[sqrtex]
