Sure. I was even able to reproduce this solely using subversion 1.4.3
and the file: repository access scheme. Copy the attached files to some

export SVNPREFIX=<installed location of subversion>
svnadmin create foo
cat pre-commit | sed -e "s:/path/to:$PWD/foo/hooks:" > foo/hooks/pre-commit
chmod +x foo/hooks/pre-commit
cat check-mime-type.pl | sed -e "s:/path/to:$SVNPREFIX/bin:" >
chmod +x foo/hooks/check-mime-type.pl
svn co file:///$PWD/foo bar
cd bar
echo "this is bar" > bar
svn add bar
svn propset svn:mime-type text/plain bar
svn propset svn:eol-style native bar
svn ci -m "initial state"
svn rm bar
echo "this is bar, again" > bar
svn add bar
svn propset svn:mime-type text/plain bar
svn propset svn:eol-style native bar
svn proplist -v bar
svn ci -m "checkin replacement of bar"


# The pre-commit hook is invoked before a Subversion txn is
# committed. Subversion runs this hook by invoking a program
# (script, executable, binary, etc.) named 'pre-commit' (for which
# this file is a template), with the following ordered arguments:
# [1] REPOS-PATH (the path to this repository)
# [2] TXN-NAME (the name of the txn about to be committed)
# The default working directory for the invocation is undefined, so
# the program should set one explicitly if it cares.
# If the hook program exits with success, the txn is committed; but
# if it exits with failure (non-zero), the txn is aborted, no commit
# takes place, and STDERR is returned to the client. The hook
# program can use the 'svnlook' utility to help it examine the txn.
# On a Unix system, the normal procedure is to have 'pre-commit'
# invoke other programs to do the real work, though it may do the
# work itself too.
# *** FOR REVISION PROPERTIES (like svn:log or svn:author). ***
# This is why we recommend using the read-only 'svnlook' utility.
# In the future, Subversion may enforce the rule that pre-commit
# hooks should not modify the versioned data in txns, or else come
# up with a mechanism to make it safe to do so (by informing the
# committing client of the changes). However, right now neither
# mechanism is implemented, so hook writers just have to be careful.
# Note that 'pre-commit' must be executable by the user(s) who will
# invoke it (typically the user httpd runs as), and that user must
# have filesystem-level permission to access the repository.
# On a Windows system, you should name the hook program
# 'pre-commit.bat' or 'pre-commit.exe',
# but the basic idea is the same.
# The hook program typically does not inherit the environment of
# its parent process. For example, a common problem is for the
# PATH environment variable to not be set to its usual value, so
# that subprograms fail to launch unless invoked via absolute path.
# If you're having unexpected problems with a hook program, the
# culprit may be unusual (or missing) environment variables.
# Here is an example hook script, for a Unix /bin/sh interpreter.
# For more examples and pre-written hooks, see those in
# the Subversion repository at
# http://svn.collab.net/repos/svn/trunk/tools/hook-scripts/ and
# http://svn.collab.net/repos/svn/trunk/contrib/hook-scripts/
