Tenuto + accent

[Martín Rincón Botero]

(See https://lists.gnu.org/archive/html/lilypond-user/2022-04/msg00314.html for 
a workaround).

Dear list,
compare:
{
c'4->-.
}

with:
{
c'4->--
}

This last compound articulation is wrong. In the first example the staccato 
(even though it was typed after the accent) is correctly printed (immediately 
below the note-head) and then the accent. With tenuto-accent, apparently 
Lilypond expects you to type both articulations in the right order, which 
indeed prints a correct articulation:
{
c'4--->
}

Enhancement request: tenuto-accents should be printed correctly independently 
of the order of input, just like staccato-accents.
Regards,
Martín.
