I found this symbol in the following french music theory reference :
Théorie de la musique, A. Danhauser, edition 1996
pages 159 and 160
see attached scanned excerpts. (please don't discard it on the mailing list)
quick translation :
** p159 **
"Durant un temps déterminé ... "
-->During a specified time, instrumentist may have to repeat a pitch
or a melodic phrase, each time as fast as possible.
"On trouve également un autre symbole ..."
There is another symbol to indicate the repetition of a group of
pitches, out of tempo.
"Ici, le trait est répété ..."
here the enclosed melodic figure has to be played nonstop during two
measures up to F sfz.
** p160 **
"Ce symbole signifie"
This symbol means indicated pitches have to played in a so-called "ad
libitum" order (any order you decide) that must be renewed each time.
Duration of pitches are often textually indicated.
examples :
"play these pitches with a long or a very long duration value"
or
"play these notes by groups of 2, 3 or 4 with very short durations"
