gb4e leaves extra space before translation

Question

gb4e leaves extra (unwanted) blank line space between gloss and translation. Same problem as here: Why is the gap between the translation and the last line of the gloss so wide in my interlinear gloss? but the answer there (cgloss.sty) doesn't always fix the problem. In the following code - the third \glt line has a wide space before it:

\documentclass{article}
\usepackage[safe]{tipa}

\usepackage{gb4e,cgloss}

\begin{document}

\begin{exe}
    \ex \gll kma t'-\textschwa{l}\v{c}qu-(\textgamma)in \\
    {\sc 1sg}  {\sc 1sg.sub-}see-{\sc 2sg.obj} \\
    \glt `I saw you.' (S1:71)

    \ex \gll q-\textschwa{l}\v{c}qu-{\textbeta}um kma\\
    {\sc 2.irr-}see-{\sc 1sg.obj} {\sc 1sg}\\
    \glt `Look (at) me.' (S1:75)

    \ex kma t-k'o{\textbeltl}-ki\v{c}en \\
    {\sc 1sg} {\sc 1sg.subj-}come-{\sc 1sg.subj} \\
    \glt `I came/arrived.' (S3:13)

\end{exe}
\end{document}

Answer 1

The problem is in a typo in your last example: you forgot the \gll line.

\documentclass{article}
\usepackage[safe]{tipa}
\makeatletter
\def\new@fontshape{}% Needed due to changes in LaTeX kernel
\makeatother

\usepackage{gb4e,cgloss}

\begin{document}

\begin{exe}
    \ex \gll kma t'-\textschwa{l}\v{c}qu-(\textgamma)in \\
    {\sc 1sg}  {\sc 1sg.sub-}see-{\sc 2sg.obj} \\
    \glt `I saw you.' (S1:71)

    \ex \gll q-\textschwa{l}\v{c}qu-{\textbeta}um kma\\
    {\sc 2.irr-}see-{\sc 1sg.obj} {\sc 1sg}\\
    \glt `Look (at) me.' (S1:75)

    \ex \gll kma t-k'o{\textbeltl}-ki\v{c}en \\
    {\sc 1sg} {\sc 1sg.subj-}come-{\sc 1sg.subj} \\
    \glt `I came/arrived.' (S3:13)

\end{exe}
\end{document}

BTW, the two-letter font changing commands (\bf, \it, \rm, \sc, etc.) are deprecated and should really not be used. Instead, it's better to use \textbf{<foo>}, \textit, \textrm, \textsc or their switch counterparts (\bfseries, \itshape, \rmfamily, \scshape) See Will two-letter font style commands (\bf , \it , …) ever be resurrected in LaTeX?.
