This is a bug, or at least a non-optimal behaviour.

Luckily, it has already been improved in the current GIT repository.

With this version, your input is transposed as expected, without the need for 
"--no-strict":

===
$ printf "1\t2\t3\ta\n4\t5\t\tb\n6\t7\t8\tc\n" | datamash transpose
1       4       6
2       5       7
3               8
a       b       c
===

I hope to release a new version (1.0.7) soon.
Until then, you can get the code from:
http://files.housegordon.org/datamash/src/datamash-1.0.6.42-36cd.tar.gz

Or directly from the git repository:
http://git.savannah.gnu.org/cgit/datamash.git/
