Well, beside the improvement (tcl-end-of-defun and tcl-eval-defun does
work better), which I again confirm I see one more (unexpected and
unwanted) effect.

With emacs 26.1:

- emacs -Q

- M-x tcl-mode

- Insert

do {
foo            

Indent the second line ("foo") with <Tab> and you get

do {
    foo


Do the same with master and you get

do {
foo

the second line ("foo") does not get indented with <Tab>. 

Something is special with "proc". If there is a proc before such code as
above the indentation works even with master, e.g. with

proc do {script} {
    eval $script
}

do {
foo

the line "foo" will be indented by <Tab> with 26.1 and master.
