I'm using dash 0.5.13 with the two patches

[PATCH] expand: Fix off-by-one bug in expmeta [PATCH] expand: Fix typo in pmatch for wildcard search

as /bin/sh and get the folling breaking while building GNU inetutils:

Note: dash 0.5.12 works as expected with inetutils.

Thanks for the report! This is due to an unintended change in behaviour of echo '\"'. Thie patch should fix the problem.

Only dollar single quote should eat the backslash character before a quote. Make the skipping of the backslash conditional on mbchar in conv_escape.
