;; Sometimes, when completing path names and immediately
;; hitting RET, `completion-in-region-mode' still seems to be
;; active; this often happens when calling cd. Then,
;; `post-command-hook' still contains
;; `completion-in-region--postch', which calls some `pcomplete'
;; function to determine whether completion mode should exit.
;; However, after RET (i.e., `eshell-send-input'), we only have
;; an empty prompt, and `pcomplete' just computes all possible
;; functions for completion (doesn't show it, though). This
;; introduces a noticeable amount of delay, which is annoying.
;; Expliticly disabling `completion-in-region-mode' before
;; sending input seems to alleviate the problem.
