It would be possible to offset both of them, but I think you might be
better served by approaching the problem from a different angle. You can
control the relative positioning of stem and note head through
'stem-attachment, which is a property of NoteHead. The flag will move
along with the stem. Also, the stem will end in the same place as an
ordinary stem. Try this (the color override is useful to show the start of
the stem):
\version "2.15.38"
customStemAndFlag =
\once \override NoteHead #'stem-attachment = #(lambda (grob)
(if (eq? (ly:grob-property grob 'direction) UP)
'(-0.5 . -0.5)) '(0.5 . 0.5))
\relative c'' {
%\override Stem #'color = #red
\stemUp
c8 \noBeam
\customStemAndFlag
c
\stemDown
c \noBeam
\customStemAndFlag
c
}
HTH,
David
