keyword: suppress keyword expansion while 'hg fetch' for internal merge

Before this patch, 'hg fetch' may cause unexpected conflict, if 'hg
fetch'-ed changes are located near lines in which keywords are
embedded, because keywords are substituted with other strings in the
working directory.

This patch suppresses keyword expansion while 'hg fetch' for internal
merge by adding 'fetch' to 'restricted' command list like 'merge'.

This patch uses 'hg import' to safely create the new head to be merged
at succeeding 'hg fetch', because:

  - branch of revision #10 is different from one of #11 in 'Test'
    repository, so just 'hg fetch -r 11' doesn't cause merging between
    them

    this means the new head should be created manually.

  - 'hg import' is easier and safer than 'cat <<EOF' and 'hg commit'
    to replay same changes including special characters like '$'

    safeness of 'hg import' with keyword extension is already examined
    in 'test-keyword.t'.
