Incorrect nextbegindifference for \GreBarSyllables

[davidweichiang]

1. If a word is interrupted by a bar syllable, it seems that the bar and its surrounding space are not counted when deciding whether to hyphenate the word. I think the first example should have a hyphen, but doesn't:

\gresetinitiallines{0}
\gabcsnippet{a(g)(,)a(g)}
\gabcsnippet{a(gg)(,)a(g)}

Output (with barspacing lines turned on):

2. If there are two bar syllables in a row, the first syllable's nextbegindifference does not include the space before the second bar, but the second syllable's begindifference does include the space before the bar. This can make the two syllables collide:

\gabcsnippet{a(g)a(,)baaaa(,)a(g)}
