Me again. While working on the previous report, I came across a strange
bug with \letterspacefont: If the first control sequence is a single
character, pdftex will abort with
!pdfTeX error: pdftex (file ???+100ls): Font ???+100ls at 600 not found
This does not happen with all fonts, e.g., in the following example,
cmr10 would be fine, as would be changing \y to \xy:
\font\x=cmr12
\letterspacefont\y\x 100
\y y
\bye
