The only "documentation" of \endSpanners available in the LilyPond
distribution today is the regression test example called
music-function-end-spanners.ly
A quick look at the implementation reveals that the \endSpanner function
takes one argument, which is a music expression (and cannot be a sequence
of notes, just a single so-called EventChord), so Max's comment seems
correct.

So that's a brief explanation of the function. Could you please insert
the following at the very bottom of 8.1.2 "Text and line spanners",
immediately before the "see also"?
%%% BEGIN DOC ADDITION %%%
The music function \endSpanners terminates spanners and hairpins after
exactly one note.
\new Staff {
\endSpanners
c'2 \startTextSpan c'2
c'2 \< c'2
}
When using \endSpanners it is not necessary to close \startTextSpan
with \stopTextSpan, nor is it necessary to close hairpins with \!.
%%% END DOC ADDITION %%%
One thing I realize now writing this update is that I don't know if
there is a way to turn \endSpanners *off* at some point in input and
return to specifying spanner (and hairpin) endpoints manually.
Compiling your example (with version 2.11.34) results in the warning
"unterminated (de)crescendo", and the hairpin is not present in the
pdf output. After inserting \endSpanners *twice*, however, like so:
%%% BEGIN CODE %%%
\new Staff {
\endSpanners
c'2 \startTextSpan c'2
\endSpanners
c'2 \< c'2
}
%%% END CODE %%%
... the warning disappears and the hairpin is visible in the way you
described. Which leads me to think that \endSpanners only applies to
the spanner immediately following the command (similar to a "\once").
It's just a guess, though, without having looked at the code.
Best,
Max (who should finally learn not to read emails while trying to get
his work done :))
